Live Wilderness Adventure

Chapter 647 Blizzard

"In fact, some people say that the red-haired Eric in One Piece is the red-haired Eric. I'm not sure about this. It belongs to hearsay. Just listen to it."

Bi Fang took a breath.

Walking on the ice field was too tiring. For safety, he could not walk too fast, otherwise the possibility of falling would increase greatly.

And standing on the unsheltered ice field, one can clearly feel the heat being taken away from the body, even if the amount of exercise is not large at all, the physical exertion is not small at all.

"In polar regions, it's important to cover your entire body against cold temperatures and strong winds, especially your head and feet, and don't stop."

"We have a reserve energy in our body, that is fat, and by consuming fat, we can also generate calories, so I have been eating high-calorie foods these days, drinking milk tea as water, eating donuts as rice, and cheese as seasoning, just to Gain weight."

[Hiss, let me tell you, I vaguely feel that Lao Fang has gained a lot of weight]

[Good guy, I gained ten catties after eating this meal]

Bi Fang breathed a sigh of relief, feeling no warmth on his face at all.

The sun's radiation made the temperature rise a lot, about minus thirty-five, but it was still very cold. The huge temperature difference was like a giant water pump, pumping out all the heat, full of horsepower.

"The best way is to keep walking, which can ensure blood circulation in the body and avoid sweating caused by excessive exercise."

"If you start sweating, you must loosen your clothes and ventilate in time. If you are soaked in sweat, the warmth retention effect will be reduced. At the same time, pay attention to keeping the clothes clean. Sand, dust and grease will block the gaps in the clothes and reduce the effect of isolating cold air. .”

After walking for nearly four hours, the surrounding area was still empty.

Bi Fang stopped at the same spot and looked around. At this time, the sun had reached the highest point, but it was still very low, as if it couldn't rise up. It made people feel that 30 degrees is enough to be uncomfortable in normal times.

"I can't go any further. The ice sheet is bigger than I imagined. It may take more than two days, maybe three days. Taking advantage of the relatively high temperature now, we have to stop and plan how to spend the night."

The width of the ice sheet is larger than Bi Fang imagined. Every summer, the sea ice melts, and then it starts to freeze in autumn. But it seems that this year's sea ice freezes very fast, and maybe this winter will be even colder.

"Today's weather is actually very good. You see, the air visibility is very high." Bi Fang pointed around.

Indeed, the air here is terribly clean, except that it is as cold as a knife, and the sea ice stretches as far as the eye can see, and the spread is light blue and pure white, as well as warm yellow sunlight.

The world is very simple and elegant.

"If you are forced, such as a plane crash, or other reasons to reach the situation I am in, then this is the best time to call for help. The skills in this area are similar to rescue in mountains."

"Bright colors and linear shapes are easier to spot from the air. Even a black piece of clothing can be seen from a great distance on the bare snow."

"Burning animal fat produces smoke. You can also use ash and burnt debris to mark snow and ice, and don't skimp on expensive calfskin belts."

"Search and rescue flights can only be done in sure good weather conditions, so you have to be prepared. Helicopters are unlikely to rescue you in a snowstorm unless you have a Fortune 500 company in your team family's daughter."

Bi Fang made a joke. He still remembers his second live broadcast where someone questioned the unreasonable speed of the rescue. It was a drama of the director.

In fact, it can only be said that these people do not understand wilderness and human power.

"Snow rescue, most of them may use planes with sleds. There are not many such planes in the world, so you need to find a place to use as a runway for landing. The place doesn't have to be very flat, but it must not have Obvious, something that could damage the aircraft."

"Larger and hard undulating snow fields formed by the wind, commonly known as 'snow ridges', are impossible to land on. Level ground about 100 meters long and covered with a thin layer of snow is the most ideal landing site. , this kind of place would also be a good place for us to stay, because then we can spot polar bears approaching at a glance."

Bi Fang squatted down, began to cut the ice with a knife, and said.

"Contrary to what many people think, the polar bear's hair is not actually white, and its skin is even black. The reason why it looks white is because it has two layers of hair. The outer layer is about 5-15 cm long. Made of a protein called keratin, it's hollow rather than solid."

"This peculiar structure, while receiving sunlight, can store sunlight in the hollow hair, and then refract it at a certain angle. At this time, the polar bear's hair will look pure white, and it is very difficult to hide in the snow. It was found that it was almost exactly the same as the surrounding environment."

Therefore, a flat and open environment around is very necessary, and the existence of the giant can be seen at a glance.

"The reason for this is that this kind of hollow fur is waterproof and heat-insulating, which is equivalent to the onion dressing method we use, which can not only meet the needs of mimicry, but also keep warm."

Bi Fang also mentioned the onion dressing method before, that is, compared with thick clothes, multiple thin clothes with the same thickness will be more insulated, and a thin air layer is formed between the clothes, which plays a role in blocking heat loss Effect.

And it is also convenient to put on and take off, so as to achieve the effect of using in different environments.

For example, Bi Fang will build a shelter next, and the amount of exercise is slightly higher, so you can take off one layer to avoid sweating.

As Bi Fang moved forward, the snow on the ground had begun to accumulate, which was good news, indicating that he was approaching land.

"I have always said before that one of the keys to survival is to know where you are. As long as you know where you are, you can be prepared for many things."

"Greenland's high latitude, high average altitude, and glaciers cover it all year round, causing a cold high pressure to exist on Greenland all year round. Due to the cold high pressure, the temperature in Greenland is low, and there are many cold currents around Greenland. It further promotes its cooling effect.”

"But do you still remember Svalbard? The latitude is higher, but the temperature is very warm. This is because the Atlantic warm and humid air flow is very strong, which will bring abundant precipitation to the coast. The Atlantic warm and humid air flow reaches its peak in winter and is very strong. .”

"When the two collide, it is the most common cold and warm front system in geography textbooks, but instead of raining, it snows, so Greenland has many blizzard days."

"However, Greenland itself is surrounded by cold currents, and due to its terrain, it cannot be driven straight in. It will only snow in the edge areas in autumn and winter to supplement the ice cover to a certain extent. At this time, the sea surface has just started to freeze and continues to spread outward."
